Ikea wants you to take photos of its new environmentally-friendly furniture line so badly that it's giving you a cardboard digital camera to do it with. The Knappa is made almost entirely out of cardboard, runs on two AA batteries, and takes about 40 pictures at a time.

The camera is being released as part of the company's new PS line, which is due out later this year.

The Knappa follows Ikea's recently announced Uppleva line, which is a line of furniture with integrated home entertainment devices such as HDTVs and speakers. The Uppleva line doesn't come out until 2013 (fall 2012 in Europe), but we should start seeing the Knappa as soon as late summer.

Ikea plans to give the Knappa away to people who purchase pieces of the company's PS line. The company wants people to take photos of the furniture in their own homes, and then upload the images to Ikea's website.

According to industrial design blog Core77, the Knappa isn't exactly the best camera around (just like Ikea's furniture, perhaps). The pictures supposedly look like they were taken on "one of those early cellphone cameras," and the camera itself "barely even qualifies as an ad hoc solution for a first-time photographer."

The first pieces of Ikea's PS line will hit stores in August, but the Knappa will only be offered in "select" stores worldwide.
